I doubt that. I would like to see you prove it. I do not think this would cause even a 0.1°C difference. Can you suggest a way to deliberately introduce such a small gap? Perhaps with a thin piece of paper instead of an air gap? > Dont you see that Rossis arrangement was horrible and disqualifies him and > Levi and Focardi to do such measurements? > No, I do not. I have measured temperatures on pipes several times. As far as I know, this method works fine. Actually Rossi did a better job than most people do. Your other assertions about bubbles of air in the pipe are untrue. The metal of a steel or copper pipe averages out the temperature quite nicely. Miles and others showed this with a copper sheathed calorimeter with an air space at the top and thermal gradients inside. Probably braided pipe does not work as well. If you are so sure this was "horrible" I suggest you do a test and prove it. Even a rudimentary test such as the one I did shows it is not horrible. Rossi's methods were much better than mine. - Jed
